The following excerpt is from Shaffy Gutteridge, 2010 ONSC 5975 (CanLII):
An unreasonable decision is one which is generally not supported by any reasons that can stand up to a somewhat probing examination. The decision may satisfy the reasonableness standard if it is supported by a tenable explanation, even if the explanation is not one which the review court finds compelling. Law Society of New Brunswick v. Ryan, (2003) S.C.C. 20 at paras. 55-56.
